FIELD OF THE INVENTION
The present invention relates to cleaning apparatus and more particularly to a portable cleaning apparatus for showers and other areas that are prone to getting wet and retaining fluids.
BACKGROUND OF THE INVENTION
Areas that are meant to deal with water, such as showers, kitchens, pools, hot tubs, etc. typically retain a portion of the water on its surfaces after use. This is especially true for commercial kitchens, such as in a restaurant, and bathrooms, such as in a workout facility, which handle large volumes of water and other fluids. As such, because a wet, damp environment is ripe for the growth of soap scum, mold, mildew and other bacteria that can have deleterious health effects on people using these facilities, it is imperative that these areas are cleaned well and disinfected correctly. In fact, for some commercial areas, professional cleaners may be required to ensure that the area is completely cleaned and/or disinfected.
In general, to adequately clean wet areas (such as a shower stall, bathroom, kitchen, etc.) multiple steps are typically used. The first step involves dispensing a cleaning fluid/liquid onto the surface or area that needs to be cleaned. This is usually accomplished via one or more spray bottles which contain a cleaning solution wherein the cleaning solution is sprayed onto the surfaces to be cleaned to cover the surfaces. The surfaces are then rinsed thoroughly to remove the cleaning solution from the surfaces. This is important because the cleaning solution may be caustic in nature. Unfortunately, however, these cleaning steps require multiple apparatus thereby requiring the cleaning person to carry large amounts of cleaning supplies, such as cleaning solution, cleaning solution dispenser, and a water container with enough water for rinsing the surfaces being cleaned. Accordingly, this makes cleaning these areas laborious, time consuming and inefficient.
SUMMARY OF THE INVENTION
A portable shower cleaning article is provided and includes a first container, wherein the first container defines a first container cavity for containing a rinsing fluid, and a pump, wherein the pump is associated with the first container cavity. The portable shower cleaning article further includes a dispensing hose, wherein the dispensing hose includes a hose input end communicated with a hose output end via a hose cavity, a trigger valve, wherein the trigger valve is associated with the hose output end and defines a trigger valve input end communicated with a trigger valve output end via a trigger valve flow cavity and a second container, wherein the second container is removably associated with the trigger valve output end and defines a second container cavity for containing a cleaning fluid. Additionally, the portable shower cleaning article also includes a dispensing nozzle, wherein the dispensing nozzle is associated with the second container and in flow communication with the second container cavity, wherein the pump is configured to pump the rinsing fluid through the hose cavity, through the trigger valve flow cavity, into the second container cavity and out of the dispensing nozzle under a flow pressure.

This would advantageously allow a user to use the cleaning device 100, 160, 200 while having the first container 104, 162, 204 being constantly filled with water.
In accordance with one embodiment of the invention, a method 300 for operating the cleaning device 100, 200 is provided and includes filling the first container 104, 204 with water or other rinsing fluid, as shown in operational block 302. The first container 104, 204 may then be sealed and the second container 106, 206 may then be filled with a cleaning fluid/solution/chemical, as shown in operational block 304. This may be accomplished by removing the second container cover 144, disposing the cleaning fluid/solution/chemical into the second container cavity 142, 218 and associating the second container cover 144 with the second container 106, 206 to securely cover the second container opening 140 and enclose the second container cavity 142, 218. The trigger valve input end 134 is securely associated with the hose dispensing end 128 and the trigger valve output end 136 is securely associated with the second container cover input port 146, as shown in operational block 306. The pump 108, 208 is then operated to cause the water contained within the first container cavity 120, 214 to flow through dispensing hose 110, 210 and into the trigger valve 112, 212 under pressure, as shown in operational block 308.
The trigger valve 112, 212 is then operated to cause the water contained within the dispensing hose 110, 210 and the trigger valve 112, 212 to flow into the second container cavity 142, 218 to mix with the cleaning fluid/solution/chemical within the second container cavity 142, 218 and flow out of the second container cover output port 148 in a pressurized stream and onto the surfaces to be cleaned, as shown in operational block 310. The cleaning fluid/solution/chemical may be left on the surfaces to be cleaned to allow the cleaning fluid/solution/chemical to soak on the surfaces and interact with the dirt/grease/germs and/or the cleaning fluid/solution/chemical may be agitated by scrubbing/rubbing the cleaning fluid/solution/chemical on and/or into the surfaces being cleaned. The second container 106, 206 is then disassociated from the trigger valve output end 136, as shown in operational block 312, and the trigger valve 112, 212 is operated to cause the water/rinsing fluid located within the first container cavity 120, 214 to flow out of the trigger valve output end 136 under pressure, as shown in operational block 314, to rinse the surfaces that were covered with the cleaning fluid/solution/chemical from any residue from the cleaning fluid/solution/chemical. If the first container cavity 120, 214 is depleted or low on water/rinsing fluid, more water/rinsing should be added.
It should be appreciated that one advantageous feature of this invention is that the cleaning device 100, 200 generally uses a pressure of approximately 60 psi. Accordingly, the pressure allows for the cleaning fluid/solution/chemical to be disbursed adequately to clean surfaces but is not large enough to cause over spray and/or damage the structure being cleaned. Essentially, when the water from the first container cavity 120, 214 interacts with the cleaning fluid/solution/chemical contained within the second container cavity 142, 218 it mixes with air and foaming occurs. The foam is then diffused through the nozzle.
